I am fairly certain that nobody in the Downer’s Grove, Illinois Park Department has a well-developed sense of irony. But maybe they are more concerned with mowing the grass than considering what the Constitution actually means. Or maybe they are liberals who pretend that the Second Amendment is not a civil right. Whatever the reasoning (or lack thereof), the irony in this sign i(spotted by Big Fur Hat of iOTW Report) is pretty stunning.

Hint: look at the bottom left of the picture if the irony escapes you.
